We have 3 EoIP link transporting one same VLAN for the same client.
These EoIP are set up between the same router on one side and 3 several routers on the other sides. Every goes well except for one of them. The configurations are identicals. the symptoms are as follow :
Every 20mn, the trafic inside this VLAN/EoIP goes to 0bps for a few seconds and then come back to normal. It is every 20mn, very strange, there is no script of thing like that running every 20mn on this router.
I have found nothing to explain that (interfaces errors, link issue etc ...). There are also other services propagated towards this router but not inside an EoIP tunnel and there is no issue at all. Only inside this EoIP.
Anyone got this kind of strange issue ? It's cyclic, not sure what event can trigger that every 20mn.
